find the quotient and the remainder and then verify it with division algorithum

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e. g. 98.765).

I’m really confused and need to learn this

How do you find the distance of each number from the mean
